The rise in sea level is one of the main effects of global warming. Over the last 100 years, the global sea level has risen by about 10 to 25 cm as was said in the environmental program of the united nation. It is noticed that it is not easy to record sea level due to the vertical movements of the earth and other natural unclear factors. It is likely that the sea level is directly proportional to the temperature concurrent increasing over the last 100 years. Other factors are more difficult to be noticed, but it was observed from the high sea level rates that there has been a leaking in the big ice sheets of Greenland and Antarctica that supports the raising in sea level. The insufficient data about this ice sheet made it some kind of mysterious over the last hundred years. Finally I can say that sea level rise is a seriouse problem and goverments have to integrate to find some logical solutions.

what we have to do to reduce the sea level?
for example some countries build dams and wall defences to protect their lands from high sea levels.
